Aluminum subframe connectors not fitting???

[Chris Benvie]

I brought my SHO into the tranny shop for the new tranny and gave them the Aluminum subframe bushings, they took out the urethane ones and said the aluminum ones don't fit. Anyone ever have this problem?? He said something about hogging out holes, ahh whatever, someone let me know.

I did here that there was some fitment issues on some of the Alum. SFB. Not sure what the fix is - maybe contact whoever you bought them from and ask them.

Chris -
Subframe BUSHINGS. Those are the round discs (2 pieces per corner, 4 corners). Subframe CONNECTORS are the long welded unibody connectors that reduce body flexing.

I know, it's just the "hearts" messing up your brain & all... wink

Yes, mine would not slide right in either. I just had to take a die grinder and clean up the holes in the sub frame a tad. After that they slid right in. Took 5 minutes.

yes, u do need to make holes inside the car behind the front floor mats. if u have the sub frame BUSHINGS, read the directions that came with it, it will then make sense..........................

the holes for the bolts on mine were to small
and I ended up with 2nd deg. burns on my hands from trying to tap them with the recall kit bolts(i.e. NEW) and a air impact
when I had tapped them all they would not pull the subframe tight aginst the car due to the fact that they were now threaded

Just as RJ-92 said. It is probably because of oxidation (rust) at the inside diameter of the subframe holes. Just use a Dremel tool, drill or round file to grind the hole just enough to get a press fit for the bushing. You do not want it to slide in freely. It should be a tight fit that requires a rubber hammer to help it into place.

thanks for all your input guys, i had to go down there and show the guy, when i got there hes like i think i figured it out, shoulda just done it myself. And fred she likes the hearts alright thumbs_u haha you and kirk got a good laugh outta that one, guess we shoulda paid more attention since eric was under the engine we were holding oh well

Tapping will work but its not the right way to do it. you have to install the top first, then slide the bolt though the bottom section then screw it in. its made like that by design.

Also the factory holes in the subframe are not perfectly round (just look at the factory bushings) if the subframe needs to be filed a little bit to make round you have good bushings. if they just fall in the bushing is out of spec and not contacting all of the subframe (in hole) and will wear much faster and get looser faster.

We had this problem installing John Heer's SFB's (delrin) a while back. He had the SHOnut design. I did not like the design as compared to Mike Courtney's (which I have). They were more difficult to install and did not fit nearly as well.

We chamfered the leading edge of the bushing so it would get started in the subframe. After that, using the bolt to pull it in, it seated with a few taps of a rubber mallet.
